_______________General Description

The MAX965–MAX970 single/dual/quad micropower

fully specified single-supply operation down to +1.6V.

These devices draw less than 5µA per comparator and

to 6V (max) above ground. In addition, their rail-to-rail

input common-mode voltage range makes these com-

parators suitable for ultra-low-voltage operation.

A +1.6V to +5.5V single-supply operating voltage range

makes the MAX965 family of comparators ideal for 2-cell

battery-powered applications. The MAX965/MAX967/

MAX968/MAX969 offer programmable hysteresis and

an internal 1.235V ±1.5% reference. All devices are

available in either space-saving 8-pin µMAX or 16-pin

QSOP packages.
